Re: [Xen-devel] [Qemu-devel] [PATCH] xen: make xen-platform a default device
One issue is that -M pc didn't always work with Xen. Now it does and we
are already relying on it in libxl since
2bc047635b51abd41c917aa2b813211ee0de2c38. It is safe because all QEMU
releases from 1.6 onward work well with Xen and -M pc. Older QEMU
releases are considered ancient and unmaintained. This is what I was
referring to in my last reply. I really meant "we should move away from
xenfv and use a pc.* machine that does not create xen-platform by
default".
As you say the other issue is the version of the pc machine, especially
in relation to save/restore. However since:

libxl: Handle xen_platform_pci=0 case with qemu-xen.
we are simply calling QEMU with -M pc if xen_platform_pci=0. I think we
should change that too and backport the patch to 4.4. pc-i440fx-1.6
seems like a good choice to me.
Use "-M pc" as default seems a good idea.
Use specific version maybe too.
This way the base hardware should stay the same even if updating qemu,
is right? If yes, this should also solve possible problem like windows
reactivation request for different hardware, right?
How about create also xl parameter to select the "pc" model?
Thanks for any reply and sorry for my bad english.
